The fly was first used on that named river and proved to be successful during a weekend when a variety of surface insects were present including several types of caddis, red quills, yellow sallies, and some larger golden stones.
We all know there's really nothing much new under the sun, and this imitation is no exception to that rule. Based roughly on an elk hair caddis design, there are a few significant differences. The hook is always a TMC 200R, and the tying thread is always fluorescent orange. No hackle is used, nor is there any tail. Natural deer or elk wing hair is preferred to any of those hairs dyed or bleached.
The only other modifications we make are to sometimes add rubber legs (for terrestrials and stones) or a few strands of krystal flash built into the wings as extra sparkle.
From upper left reading clockwise around the photo are a dark bodied, black rubber leg, yellow bodied white rubber leg, krystal flash wing model, and the fly as originally tied at the lower left.
We blend a variety of materials to create what sometimes become fairly complex dubbings. Depending on the coloration desired, natural hare's ear, hairtrons, antrons, and any number of other natural and synthetic materials are combined in an effort to create a "buggy" body that will emulate the movement of palmered body or collar hackles.
Tying is extremely simple. Make a dubbing loop, insert dubbing, and tie in the back two thirds of the hook, followed by the wing, and then take two or three wraps of the dubbing over the base of the hair wing to form a somewhat large "head" for the fly. If rubber legs are added, they are tied on prior to wrapping the dubbing over the base of the hair wing. That's all there is to it. A full range of hook sizes from 12 through 22 can be utilized for different insect imitations.
The fly has been extremely successful in a wide range of conditions and for a large number of insect hatches as well as for terrestrials including hoppers, beetles, and cicadas.
Speaking of which................. the next set of photos is of a flat water type cicada pattern we've developed specifically for that emergence on the Green River below Flaming Gorge.
Clockwise from upper left are a turkey winged black rubber leg, then the same wing, but orange/black centipede legged model.
Bottom right is the same orange/black centipede leg fly, but with a gray mottled medallion sheeting wing.
Bottom left is the same fly as previous, except with black legs.
Frankly these imitations are quite time consuming to construct. Almost any standard dry fly hook will work. Our best success has been using a TMC 200R is sizes 12-16 (see WRS above). The under body dubbing is a blend of half black and half orange material.
The two mm. thickness black foam is tied in at the tail and is pulled over the first half of the dubbing (starting at the top of the back bend of the hook). The back rubber legs are then tied at that juncture. Four strands of root beer colored krystal flash are tied over the legs and then the wing material is tied in atop the krystal. (If a section of wild turkey feather is used, a preliminary coating of flexament will strengthen the wing.)
One or two wraps of the dubbing is tied over the same joint, and then the dubbing is continued on towards the head beneath the next section of foam. The foam is then tied down near the head with the last set of double legs applied next. The balance of the foam material is pulled back over the upper section of the body and is secured to create an oversized head. Any excess foam is clipped off. While an extra heavy thread is not needed to secure 2 mm. sized foam, we've used 3/0 anyway as the wider width thread tends to not cut the foam.
As might be expected, these flies are difficult to see on the water since they ride low in the film. It would be possible to tie on a bright colored piece of extra foam material over the head, but as this fly will sometimes land upside down on the stream, the artificiality of that kind of colored addition might detract from the fly's appearance and certainly would cause more refusals.
This fly design has produced outstanding results compared to the commercially tied versions available at local Dutch John fly shops. The model has been fished in tandem with those other styles and has been found to draw several times more strikes than the more commonly available bleached hair wing or strictly krystal flash wing styles.
Next. Here's another modification to a preexisting pattern known as the RS-2. We found the original to be moderately effective, but it didn't seem to have enough "attractor" quality to trigger takes in many stream flow conditions.
To give the fly a bit
more flash, the stub or emerging wing material was changed from either CDC
or some other natural feather to several strands of Krystal Flash.
For most body dubbing colors the standard pearlescent material seems to work the best.
But to more closely match an emerging BWO, we will sometimes substitute black Krystal Flash instead.
Hook sizes are generally small - in the #18-22 range. 18's for a PMD model and smaller for general purpose use. Although we fish the fly primarily as a trailer behind either a WRS or another larger nymph, we have added a few wraps of thin lead wire underneath the dubbing to get the fly down quicker.
==================================================================
The balance of the patterns shown below have been added to this page from time to time since 1997. They're shown in the chronological order that they were added. Those at the end of this list are the most recently constructed.
Complex dubbings are now being created that incorporate the "legginess" hackle feathers normally confer on an artificial, and the hackle feather flotation qualities are now being generated by waterproofing the fly at the time it comes out of the vise.
Here are a few patterns that have been extremely successful locally - where appropriate the comments in blue type face reflect current thinking about body & winging materials.
Blue
Winged Olive Variation: While our tying philosophy
continues to be to simplify & minimize materials used in construction,
this particular version of a Blue Winged Olive comparadun benefits from a
bit more complexity. Since our local BWO's are fairly small, we use
standard #18-22 dry fly hooks.
The tail is a few dark dun hackle fibers. Body is BWO colored quill. Wings are light or gray colored elk or deer hair tied comparadun style. The thorax region is dubbed with a combination of regular hare's mask fibers into which has been blended a small amount of BWO colored micro dubbing. This style thorax is much more realistic in appearance than is created by the use of standard BWO dubbing without the hare's ear fibers, and it is the key to the construction of this fly.
Generic
Midge Emerger: This is another very simple pattern used
primarily during late fall through early spring when the only hatches we
see on 
some
of our more fishable winter tailwaters are a variety of different
colored midges. It's tied either on straight or curved nymph hooks
(as shown here) generally between sizes 18-22.
Note that a few turns of thin lead wire can be wrapped around the body region to sink the fly without the need for split shot. The body is either black or white krystal flash. A few short light dun CDC fibers makeup the vestigial wing. The thorax is a few wraps of peacock herl. The CDC wing offers the possibility of fishing the fly in the film if desired, although generally this imitation will be fished it mid flow or towards the bottom.
Hybrid
Caddis: It probably appears heavily dressed in this scan, but
is not. In fact sparseness is it's redeeming grace. Sizes range from
#10-20. Materials are as follows: No tail, cinnamon caddis dubbing body,
dark dun body hackle (not palmered), wing is sparse (not stacked) elk hock
hair.
This fly is best tied very lightly. It imitates not only the local dominant caddis coloration extremely successfully, but also those on the Roaring Fork, Gunnison, Deschutes & McKenzie & Umpqua (Oregon). The hybrid name comes from the fact (primarily due to unstacked wing hair) that it also successfully imitates several local May fly variations. (Beginning in 1999, we built the bodies strictly with complex colored dubbings, eliminating the palmered body hackle. Dubbing colors are blended to suit the local situation. Materials include various antrons, natural rabbit fur with guard hairs, and a base of hareline or superfine standard dubbing.)
Normally it's fished as part of a double fly rig - generally with a darker green bodied version with dark wings - sometimes with an emerger or appropriate bead head.
Gray
Midge Emerger: This spring the pattern was the most
successful of all larval, emerger, or surface midges we used on Gore Creek
and the Eagle. Not an original. It comes from the book of Western Hatches
by Hafele & Hughes. (See page 194). It's described as an emerging
pupa.
We tie it locally exactly as described in the book. Sizes 18-24. Tail is ostrich herl, body is deer hair ribbed with ultrafine gold wire. Thorax is narrow gray ostrich herl. The fly was fabulous during the spring of 1997.
OS-1: A knock-off of an RS-2. The scan is not good
colorwise, but a few dark dun hackle feathers are used for the tail, a
torpedo shaped gray dubbed body and a stubby stack of grey partridge
feathers emerging from the body two thirds towards the head. Tied on
standard length wet fly hooks in sizes from 16-22.
(The BWO pattern uses olive partridge. Starting in 1999, wing stubs have all be various shades of CDC depending on the type of insect being matched. This allows the emerger to be fished nicely in the film as well as deeper.)
This has been an outstanding nymph/emerger on Gore Creek and the Eagle in the past few years.
Spent Wing May Fly: Not an original pattern, but one
that was enormously successful in 1996. Tied in all color variations to
imitate baetis, red quill, blue quill, green drake, etc. Sizes from 10-22.
Tail feathers to match the natural and body dubbing appropriate for standard may fly patterns. The wing obviously is formed from a hackle feather that has been trimmed very close to the quill. It's then tied in a figure eight over the thorax area. Hackle can be non-existent, dubbing based, parachute, or standard wrap. This type of tie can also be used for tricos in appropriate sizes and colors.
Red Midge: Another very successful Gore Creek fly
this spring (1998). Used in small sizes - either standard length straight
wet fly hook or as shown here in a curved style (2487 or 2488). Sizes were
#18-22, although larger 2X-4X long hooks in #10-16 would work as bloodworm
larva in lakes.
No tail - or a few partridge feathers. Body is micro sized red v-rib. 8-0 Black thread for a head, and there is a barely visible vestigial wing pad of antron or other bright material just behind the head.
Egg
Flies: The left one is a simple glass bead fly. Number of
segments are dependent on the hook size. Right fly is a crosscut
scintilla. The left one is more original and some days is superior to the
scintilla, but on balance the scintilla would be preferred.
Tie the glass bead by over wrapping the hook with florescent orange thread. Slip on the beads and tie the thread off at the bend of the hook. A drop or two of super glue secures the package.
For the scintilla model create a dubbing loop of 6/0 or 8/0 orange thread and fill it with amber or similar shade of scintilla. Keep the dubbing sparse and before wrapping, cut it close to the thread. Wrap the fly with figure eight motions. This pattern is incredibly lifelike when wet. The "yolk" is astonishingly realistic.
Light Yellow Stone: Despite it's benign appearance
this was probably the most successful fly of the 1999 season through
mid-August. It was developed to roughly simulate the many small
yellow stones we locally encounter on the Eagle and Roaring Fork Rivers.
Tied in sizes 14-20 on 2X long dry fly hooks, use a PMD blend body dubbing material. The full length forward tied hackle is either brown or light dun. Wing can be various shades of bucktail or elk hair. Best color this season was pure white. Start the dubbing, then tie in the wing. Overlay the wing with a few wraps of dubbing to the head, and then tie in the hackle starting at the tail of the fly forward all the way to the head in stimulator fashion. Smaller sizes (16-20) seem to be the most useful. (Again beginning in 1999, the body is strictly complex dubbing material. The fly is astonishingly versatile. We've successfully used it to imitate a variety of yellow, green, and golden stones, as well as green drakes and grasshoppers. Obviously it's tied in larger sizes to match these other insects.)
Dark
Stone Nymph A generic stone we tie on 2-3X long nymph
hooks in sizes from 10-20. This may be the best all around
local nymph pattern - superior to prince's and other more realistic
stones.
Use brown thread. Tails are dark brown or black goose biots. Body is the most interesting feature. Make up a peacock herl dubbing brush on the spot. Depending on the size of the fly, tie in butt first 2-4 pieces of herl; then tie in a piece of fine copper wire same length as the herl. With a hackle plier gently wind those part together and begin wrapping on the body. Towards the thorax the brush can be lapped back & forth to add mass to that section. Tie in appropriate sized black hackle at the head and take 3-4 wraps. Pull a previously tied in dark turkey flat section over the top of the hackle & tie in at the head. Do not overdress any part of this fly.
Yellow/Golden
Stone Similar to the above, but tied with brown biots, brown
turkey flat wing pads and light brown hackle. Again with or without
a gold or other colored bead head. Only difference is body
preparation and that can be any light olive or PMD colored dubbing.
I usually run a section of yellow flashabou from the tail to the head for
segmentation and sparkle. Sizes as above. Again, do not
overdress.
Caddis
Emerger This is really just an adaptation of a
Lafontaine caddis. Here we seem to have better luck below the
surface during the blizzard-like spring caddis hatches. So this fly
is generally used with a small gold bead head. We use various colors
of antron for the shuck, sometimes trailing the fly, sometimes just
covering it. For a body simply use appropriate wraps of peacock
herl. Partridge in different shades makes the wing.
Rabbit Bugger A variation on the
conventional wooly bugger. Since our personal tying philosophy is
moving away from the use of hackles, this construction seems to work well
in terms of the way the body moves and pulsates in the water. The
image on the left is that of the bugger when dry & the one on the
right is after it's wet.
Use any desired type of weighting device - from the painted lead eyes noted here to other metal eyes, cone heads or bead heads. The tail is a clump of any colored marabou with a few strands of appropriately colored krystal flash of the same length. The body is simply regular rabbit fur cut from the skin strips & placed in a dubbing loop much like any other dubbing would be used. Continue the dubbing up and over the eyes to create a fuller head. Sizes range from 6-14 on 3X or 4X long streamer hooks.
Gunnison
Hopper Synthesized from a number of other hopper
imitations. Body is yellow foam colored with an olive prisma
pen. Legs are any mottled green rubber leg material. Under
wing is natural elk body hair and over wing is a tent folded section of
turkey feather. Coloration is a decent general match of the
grasshoppers common here in Colorado.
Caddis
Pupa This pattern showed up in one of the major fly
fishing publications this spring (2003). Developed by a guide from
the Salida area we modified it slightly but kept it mainly intact. #
16 standard length dry fly or nymph hook with 3/32 bead head in a variety
of colors. After body is dubbed tan or brown hare's ear, sometimes
simply peacock herl, followed by a few turns of partridge and a sparkly
dark dubbed thorax. Antenna are two pheasant tail feathers.
As an option, we'll sometimes tie in a swath of antron fibers behind the head and loop them back around the rear of the body along the line of a Lafontaine emerging pupa.
